What Are Dubia?

The Dubia roach (Blaptica dubia) is a medium-to-large cockroach species native to Central and South America. Males grow up to 4 cm with wings, while bulkier females reach over 4.5 cm with a darker abdomen.

Despite having wings, male Dubia roaches cannot fly, and both males and females are poor climbers, making them easy to store and handle. In captivity, they are slow-moving, odor-free, and non-invasive, meaning they won’t infest your home or cause unwanted surprises.

Forget what you know about cockroaches—Dubia roaches are clean, quiet, and the perfect hassle-free feeder insect.

Why Dubia Roaches are
The Best Feeder Roach:

More Nutritious – High in protein (up to 23%), low in fat, and easier to digest with a soft exoskeleton.

No Escape Risk – Unlike other roaches, dubias can’t climb smooth surfaces, jump, or fly, making them easy to contain.

Longer Lifespan & Less Die-Off – Live up to 2 years, unlike red runners or discoids, which die off quickly.

No Odor or Noise – Unlike crickets and other roaches, dubias don’t chirp, stink, or scratch inside enclosures.

Won’t Infest Your Home – Need specific heat and humidity to survive, so escapees won’t breed in most climates.

Easy to Store & Feed – Thrive in simple setups, require minimal care, and gut-load well for maximum pet nutrition.

Keeping Dubia Roaches

Getting Started: Housing & Setup

Enclosure

  • Container: A sturdy plastic bin or glass terrarium with smooth sides works best.

  • Ventilation: Ensure there’s good airflow. Cut out a portion of the bin lid and cover it with fine mesh or screen. This prevents excess humidity and helps avoid mold growth.

Temperature & Humidity

  • Ideal Temperature: 85–90°F (29–32°C). Use a heat pad or heat tape on one side to create a warmer zone.

  • Humidity Range: Aim for moderate humidity—around 40–60%. Avoid keeping them too moist, as they can develop mold or attract mites.

Substrate & Hiding Places

  • Substrate (Optional): Many keepers go with a bare-bottom container for easy cleaning. If you choose a substrate, keep it dry and easy to replace.

  • Egg Crates or Egg Flats: Provide vertical surfaces for roaches to hide and climb on. Stack them so you can create separate “floors” and maximize space.

Feeding & Hydration

Diet

  • Roach Chow: A balanced roach chow offers a complete nutrient profile.

  • Fresh Fruits & Veggies: Supplement with carrots, leafy greens, oranges or apples for added moisture and vitamins. Avoid overly wet produce that can increase humidity and spoil quickly.

  • Oats & Whole Grains: Offer uncooked oats or bran, along with other whole grains, as a hearty, readily available food source that Dubia roaches will eagerly consume.

Water Source

  • Water Crystals or Gel: Provide hydration safely without the risk of drowning. Replace regularly.

  • No Standing Water: Open water bowls can spill and raise humidity or even pose a drowning risk to smaller roaches.

Routine Care & Cleaning

  • Remove Old Food: Check daily for moldy produce or leftover bits.

  • Spot Clean: Every 2–3 days (or at least once a week), remove any leftover food that can mold or spoil, and scoop out accumulated frass (droppings) or debris.

  • Deep Clean: Every 2–3 months, or more frequently if you notice significant waste buildup or a strong odor. For this, you’ll transfer roaches to a temporary container, thoroughly wash and dry the bin, then reintroduce the colony.

Common Questions

Breeding Tips for a
Sustainable Feeder Colony

Sex Ratio

  • Optimal Ratio: About 1 male for every 3–5 females ensures consistent mating without stressing the females.

Conditions

  • Stable Warmth: Keep temperatures in the 85–90°F (29–32°C) range. Females need consistent heat to produce oothecae (egg cases).

  • Ample Food: Well-fed roaches breed more readily. Provide a constant supply of chow, oats/whole grains, and fresh produce.

Inspecting for Nymphs

  • Birth & Growth: Females give birth to live young (nymphs). You’ll see small, pale roaches roaming around—these are the new additions!

  • Separate if Needed: Some owners separate newborn nymphs into a grow-out bin to ensure optimal growth and easy feeding.
